OK, so you've drawn my attention to it, but it doesn't say what you imply it does, nor does it have relevance, per se, for your own relationship with your boyfriend, since Batty's case is not yours and neither has he stated all the details of his circumstances, or of what the various counsellors/therapist said.
Furthermore, no counsellor worth their salt would state baldly that Batty was "...unable and unwilling to change...", since if someone is unable to change then it is meaningless, hurtful and unprofessional to accuse them of being unwilling to do so. What was probably said was that Batty was unable to change certain behaviours (because the counsellor thought that he was unable to do so) and unwilling to change others (which the counsellor thought were within his power) - but one of the most obvious things that Batty could have done is simply to leave his girl-friend and move on with his own life, but he is clearly unwilling to do so.
I suggest, therefore, that trying to make Batty's case fit your own circumstances is misplaced and unfair of you.
From the information given, Batty does not warrant being attacked by you, an attack which is primarily motivated by your own obvious dissatisfaction regarding your own relationship and which has nothing to do with Batty's
circumstances.
Having said that, if you do wish to air your own grievances regarding your own unhappy relationship, please feel free to do so in another thread, but don't subvert Batty's plea for help by doing so here.
I would also add that from the few details you have given regarding your own situation that you do have valid grounds for complaint, and that I would be happy to offer such support as I can should you decide to take the issue further.
